The Amminadav Formation is a Mesozoic geologic formation in the West Bank (Palestine). Pterosaur fossils have been recovered from the formation, in addition to several ray-finned fish and early snakes, most of which are known from the Ein Yabrud quarries.[1][2] The formation overlies the just slightly older Bet-Meir Formation, and it is uncertain whether most of the paleobiota belong to one formation or the other.
Paleobiota
[edit]The majority of species here cannot be confidently assigned the Amminadav Formation, and some may instead belong to the older Bet-Meir formation.[2][3]
